Title: Methods and apparatus for processing temperature sensitive materials
Inventor: PURDUM HOWARD E
IPC: C07H21/04
Filed: 1999-09-21
Abstract: A method and system (10) for selectively removing one component of a material thereby concentrating other components of the material are disclosed. The material is cooled to below the melting temperature of the material to form a supercooled liquid phase with heat transfer plate with cooling channels (20). Ultrasonic energy from ultrasonic drivers (42) is applied to the material to form solid phase crystals of the component to be removed. These crystals are removed to leave the concentrated product. The ultrasonic energy prevents the growth of dendrites on the crystals, resulting in the formation and removal of small crystals of the component to be removed without damage to or removal of the remaining components.  Methods and apparatuses for cryoprecipitation and chromatography are also disclosed.

Title: Method and apparatus for reduction of fm interference for fm in-band on-channel digital audio broadcasting system
Inventor: BAIRD JEFFREY SCOTT
IPC: H04H20/82
Filed: 1999-10-28
Abstract: This invention provides a method for reducing FM interference in an in-band on-channel digital audio broadcasting system. The method includes the steps of receiving a composite signal including a signal of interest and an interfering signal and normalizing the composite signal to produce a normalized composite signal. The composite signal is then multiplied by the complex conjugate of the normalized composite signal to produce a real signal. Then the real signal is filtered and the resulting filtered signal is multiplied by the normalized composite signal to produce an output signal. The adverse effects of the interfering signal in the output signal are reduced with respect to the magnitude of the signal of interest reducing FM interference in an in-band on-channel digital audio broadcasting system, thereby making it easier to detect the signal of interest. The output signal and the composite can be blended in response to the power of the real and filtered signals. Radio receivers that utilize the above method are also included.

Title: Method for increasing the flexibility of a communication network with separated call control and bearer control
Inventor: STUMPERT MARTIN
IPC: H04W88/12
Filed: 2000-06-06
Abstract: Method, communication network and software program that enables a more flexible architecture in communication networks with separated call control and bearer control. The invention enables full support of the advantages of a communication network with separated call control and bearer control when interfacing with a further network with monolithic signalling. The invention  also increases the flexibility of an existing payload connection, especially  in the case of a malfunction. The invention uses the existing signalling protocols to transfer further information. Basically, information elements a nd methods to interpret the transferred information are stored in the receivers  and senders of the information. This enables the receivers and senders of information to transmit more information than originally planned when the protocols were designed. So it is possible to identify a combination of a payload transmission device and a control node instead of a single device only. It is further possible, to identify an assignment as a further assignment. This allows the change of a current assignment for a radio acces s controller.

Title: Procede et appareil d'appel de recherche d'un terminal d'utilisateur dans le faisceau fin de gain le plus eleve d'un satellite
Inventor: SCHIFF LEONARD N
IPC: H04B7/185
Filed: 2000-07-20
Abstract: Cette invention se rapporte à un appareil et à un procédé permettant la recherche par téléappel d'un terminal d'utilisateur (TU) en utilisant un système de communication par satellite comprenant une passerelle (120, 122) et un ou plusieurs satellites (116, 118), chaque satellite produisant plusieurs faisceaux (401-416) et chacun de ces faisceaux comportant plusieurs canaux. Ce procédé utilise une étape consistant à effectuer le rappel d'une position du TU (124, 126), la position ainsi rappelée correspondant à une position du TU au moment t1 (904). Ce procédé utilise en outre une étape consistant à déterminer une région, sur la base de la position rappelée, à l'intérieur de laquelle on suppose que le TU (124, 126) est situé au moment t2 (906), ce moment t2 étant postérieur au moment t1. L'étape suivante consiste à déterminer un moment t3, lequel est égal ou postérieur au moment t2, lorsque les deux critères suivants sont satisfaits (908). Premièrement, l'un des satellites possède un angle d'élévation compris entre  theta 1 et  theta 2. Deuxièmement, toutes les positions à l'intérieur de la région mentionnée sont situées à l'intérieur de l'empreinte (400) du satellite (qui comporte un angle d'élévation compris entre  theta 1 et  theta 2. Les angles d'élévation  theta 1 et  theta 2 peuvent être déterminés à partir de la perspective de la position rappelée. Dans un variante, l'angle d'élévation peut être déterminé à partir de la perspective de toutes les positions comprises dans la région mentionnée. On s'assure ainsi que le TU (124) se trouve au point idéal (518, 522) du satellite (116) (là où le gain des signaux envoyés par le satellite est le plus élevé), lorsque le TU (124) fait l'objet d'un appel de recherche. En attendant ainsi que le TU soit situé au point idéal, pour lancer l'appel de recherche dudit TU, on obtient une consommation de puissance réduite par le satellite (116).

Abstract: An apparatus and a method for controlling oilfield production to improve efficiency includes a remote sensing unit that is placed within a subsurface formation, an antenna structure for transmitting power and communicating signals to the remote sensing unit and for receiving communication signals from the remote sensor, a casing joint having nonconductive "windows" for allowing an internally located antenna to communicate with the remote sensing unit for those embodiments in which a wireline tool is being used to communicate with remote sensing unit, and a system for obtaining subsurface formation data and for producing the formation data to a central location for subsequent analysis. The remote sensing unit is a standalone sensor that is placed sufficiently far from the wellbore to reduce or eliminate effects that the wellbore might have on formation data samples taken by the remote sensing unit. The remote sensing unit is an active device with the capability of responding to control commands to determine certain subsurface formation characteristics such as pressure or temperature, and transmitting corresponding data values to a wellbore tool. Some embodiments of the remote sensing unit include a battery within its power supply. Other embodiments include a capacitor for storing charge.  The embodiments that include the capacitor receive RF power that is converted to a DC signal for storing charge on the capacitor. The charged capacitor then acts as a power source to provide power to the internal circuitry of the remote sensing unit. When the charge is depleted to a specified point, the remote sensing unit stops transmitting to prompt the wellbore tool to transmit additional RF power to recharge the capacitor. This particular embodiment allows the remote sensing unit to be operable well after any charge of a battery would have been depleted rendering the remote sensing unit inoperable. An inventive method therefore includes providing RF power to the remote sensing unit to wake it up and to place it into an operational mode. The method further includes receiving modulated data values from the remote sensing unit that are then transmitted to the surface where operational decisions for the well may be made. In one embodiment of the invention, the subsurface formation data values are transmitted to a central location for analysis.
